A soft and gentle soul from a multigenerational family, who used to be more adventurous. While wandering off into the forests one day as a young child, he came across a violent Nuzlocke fight that left him mentally scarred. To help him come back out of his shell, Elm invited him to work as a bit of an assistant at his lab when he turned 12, which Arian took quick interest in. Through his experience at helping at his grandparents breeding centre, he was able to adapt quick to working with lab Pokémon and making sure they were well taken care of. Not wanting to get involved in Pokémon battling to any capacity though, made it too dangerous for him to do field research, so he recommended his much more active childhood friend instead.
Naturally, he gets pulled into the Rocket Revival and other issues in Johto, meaning he has to learn how to defend himself. Wanting to avoid that as much as possible though, leads him to following Ena more than the Kosora and Silver duo.
His family still runs a daycare/breeding centre, so he helps out there and on any other local ranches requiring an extra hand. A sensitive and knowledgeable soul who will probably become a vet when he’s older.
